ELECTRIC SOCKET.

Application filed April is, 1924. Serial No. 707,353

My invention relates more especially to the class of devices that areemployed for temporarily connecting a device with a source ofelectricity, and an object of my invention, among others, is to providea device of this class that shall be simple in construc- Figure 3 is aview in lengthwise central section through said socket showing theposition of the parts when the socket is disconnected.

Figure 4 is a view similar to Figure 3, the section however being brokenout and illustrating the position of the parts'wh'en the socket isconnected to a device.

Figure 5 shows a perspective view of several of the parts of the socketrelatively disconnected.

In the accompanying drawings I have shown a case comprising a socketthat is preferably formed in halves 6 that are united as by means ofscrews 7 in a manner common to devices of this class, this case havingan opening through which a cable 8 extends, the wires constituting thecable being attached at their inner ends to binding posts or screws 9 inany well known manner.

My improved device comprises a socket composed of two jaws, a supportingjaw 10 and a pivoted jaw 11. The supporting jaw 10 is secured within arecess 12 in the socket and the pivoted jaw is mounted upon thesupporting jaw.

It will be understood that in most installations there will be twocontacts each comprising a supporting and a pivoted jaw and each locatedin a recess 12 in the case .6, onehalf of each of said recesses beingformed in each of the case members (3, that comprise the case as awhole.

In attaching the 'pivotcd jaw 11 to the supporting jaw two posts 13 areprovided upturned from opposite sides of the jaw 10 and pivots 14project from opposite sides of the jaw'll, being formed preferablyintegral therewith. The jaw 10 has a rearward extension 15 with posts 16upturned from opposite sides thereof and preferably integral therewith,and the jaw 11 has a bent rear end constituting astrut rest 17.

A strut 18 has a cross bar 19, the ends of which are formed as pivotsthat enter open-"- ings'in the posts 16, and a spring 20 is mounted onthe strut 18 with one end thrustmg against the rest 17 and its oppositeend thrusting against the cross bar 19. The end of the strut projectsinto an opening 21 in the rest 17. -The opening 21 is so positioned withrespect to the-pivots at the ends of the bar 19 that the-end of thestrut will be on that side of aline passing through the pivots at theend of the bar 19 and the pivots 14 as to normally, under the thrust ofthe spring 20, close the jaws together, that is, force the jaw 11 towardthe jaw 10, erted to close the jaws together .will be greater when a pin22, forming a part of the electrical connection, is forced inwardlybetween the jaws so that a firm and efficient contact is made betweenthe terminal comprising the two jaws and the terminal comprising the pin22.

The description hereinabove refers to one of the terminals only, but itwill be under stood'that the two terminals common to a plug are both ofthe same construction and that the above description, therefore, appliesequally to both of such terminals.

In accordance with the provisions of the patent statutes I havedescribed the principles of operation of my invention, together with thedevice which I.now consider to represent the best embodiment thercof;but I desire to have it understood that the device shown is onlyillustrative and that the invention may be carriedout by other means andthis force exand applied to uses other than those above set out.

I claim 1. An electric socket having a recess, and a terminal located insaid recess, said terminal comprising a supporting jaw with postsintegrally formed therewith and upturned from opposite sides thereof, ajaw having pivots integral therewith and projecting't'rom its oppositeedges and located in openings in said posts, an extension from the endof said supporting jaw, means for attachu'ient ot' a wire to saidextension, and a spring thrusting against the supporting and pivotedjaws to force them toward each other. I

2. An electric socket having a recess, and

a terminal located in said recess, said' terminal comprising asupporting jaw, a jaw pivotally mounted on said supporting jaw, anextension from said supporting jaw, posts upturned from opposite sidesof said extension, a strut pivotally mounted between said posts and inengagement with said pivoted jaw, a spring mounted on said strut, andmeans for attachment of a wire to said extension.

3. An electric socket having a recess, and a terminal located in saidrecess, said terminal comprising a supporting jaw,-an extension from therear end of said jaw, said extension ending in a terminal oflset fromthe plane of said extension, posts upturned from opposite sides of saidextension, a jaw pivotally mounted on said supporting jaw, and a springhaving its thrust resisted at one end by said posts and thrusting withits opposite end against said pivoted jaw to force the jaws toward eachother.

4."An electric socket having a recess, and a terminal located in saidrecess, said terminal comprising a supporting jaw, posts upturned fromopposite sides of said jaw, an extension from the end of said jaw, postsupturned from opposite edges of said extension, means for attachment ofa wire to said extension, a jaw having pivots extending from oppositesides into openings in the posts rising from the supporting aw, saidpivoted jaw'having a strut rest with an opening therein, a strut havingpivots located in openings 'in the posts on said extension and itsopposite end located within the opening in said strut rest, and a springmounted on said strut.

5. A terminal for electrical devices, said terminal comprising two jawspivotally connected, a strut pivotally mounted upon one of said jaws andin engagement with the other jaw, and a spring mounted upon said strutand exerting a force to close the free ends of the jaws together.

6. A terminal for electrical devices, said terminal comprising two jawspivotally connected, a strut pivotally mounted upon one of said jaws, arest comprising an overturned end from the other jaw, and a springlocated on said strut and thrusting against said rest to force the freeends of said jaws toward each other.

.7. A terminal for electrical devices, said terminal comprising two jawspivotally connected, each of said jaws having spring resisting membersprojecting laterally from the jaws, and a spring disposed longitudinallyof the jaws and exerting a thrust longitudinally of the jaws and againstsaid members to normally force the free ends of said jaws toward eachother.
